I'm not sure about double profits either
However, I wouldn't be surprised in the least if Bitcoin rose to 15k in a matter of days or weeks if it ever comes to that. If it crashed from 9k to 4k in a matter of days, it won't take long to add another 5k to its current price. Moreover, the longer Bitcoin sits around 9k, the stronger will be the future price action, as has always been the case in the past. So buckle up and get ready for the coming roller-coaster
